[gdal-dev] How to use Gdal c# bindings with .NET Core

[Tamas Szekeres]

At the moment it looks like only the 3rd option below supports .net core.
However since that is a custom build, use the dependencies
(gdal_wrap.dll etc.) provided by the same bundle, ie:
https://www.nuget.org/packages/Gdal.Core.WindowsRuntime/2.3.0-beta-023
These dll-s support x64 only as far as I see.

Best regards,

Tamas
